The application of hydrated calcium silicate as filler in paper from wheat straw pulp is studied in this paper. It shows that that with the increase of dosage of hydrated calcium silicate, the stiffness of paper improves, and the whiteness and the printing color density of paper improve, but the tightness and tensile strength of paper decrease. When the dosage of CPAM is 0.45 g/kg, the tightness, tensile strength, tearing index, whiteness and printing color density reach the large value. Paper ash content increased with the increase of amount of hydrated calcium silicate, but paper ash gains is not big after the dosage of hydrated calcium silicate reaches 20%.
